Abstract: AIR/FUEL RATIO REGULATOR               ABSTRACT OF THE DISCLOSURE         An air/fuel ratio regulator for control of the movement of a fuel flow control lever on a fuel injection pump. A lever is connected to the pump lever and moved by an aneroid to change the pump fuel flow as a function of engine manifold vacuum changes to maintain a constant air/fuel ratio to the mixture charge.  A fuel enrichment lever moves to modify the movement of the fuel control lever 54 to compensate for changes in intake manifold gas temperature as sensed by a coil thermostat, to maintain the constant air/fuel ratio.  A fuel enrichment shaft having a piston is connected to the enrichment lever and to a number of spaced,interconnected but relatively movable pistons that are adjustable to change the position of the enrichment lever and therefore the air/ fuel ratio as a function of exhaust gas recirculation back into the engine, and operating the engine at cruising con-ditions for an extended period, or operating the engine at idle speed, all with leaner air/fuel ratios.  An infinite number of different air/fuel ratios can be established.

Abstract: Abstract of the Disclosure A mining machine of the type comprising a body, a dri-ven cutter mounted on the body, and an air-cleaning system com-prising ducting for conducting dust-laden air, a scrubber for applying liquid to the dust-laden air, and a demister for thereafter removing moisture from the air.  The demister com-prises a moisture separating station having a flow inlet, a flow outlet locked rearwardly of the flow inlet, and moisture separating louvers forming air channels which receive air flow from the inlet and causing moisture in the air flow to separate out and gravitate toward a lower collecting surface to be con-ducted rearwardly.  A moisture accumulating section is located adjacent a rearward end of the collecting surface to receive the rearwardly conducted moisture.  The accumulating section includes a floor, an end wall, a top wall, and a forwardly facing entrance for admitting the moisture.  A vertical gap is provided between the top wail and the inflowing moisture to in-hibit the upward travel of moisture droplets over the top wall where they would otherwise be re-entrained in the outgoing air flow.

Abstract: Abstract Of The Disclosure The extraction of polar substances, such as pure water, from a solution containing such substances is carried out in an electrical process that closely resembles natural evaporation.  By exposing the solution to a closely spaced, elec-trically charged surface, the liquid molecules of the substance become sufficiently excited and attracted to break through the surface tension and migrate to the charged surface where they accumu-late.  Alternative embodiments disclose modified means for conveying the extracted substance from the treating area.

Abstract: S.H. Frederick-5 IMPROVED HYDROTHERAPY DEVICE  ABSTRACT OF THE DISCLOSURE    A hydrotherapy device, such as a spa, whirlpool or jet stream exerciser is connected to a closed water circulation loop having a drain, a pump, a heater, a filter, a valve controlled filter bypass and injection nozzles.  The pump is equipped with a close-coupled drive motor having two sets of stator windings for allowing the selection of one of two motor speeds to achieve improved operation and greater efficiency of the hydrotherapy device.  A low motor speed is selected during periods of non-use, at which time the filter device is connected into the circulation loop so that a low water circulation rate is provided in order to maintain purity of the water.  During periods of use, a higher motor speed is selected and the filter is bypassed to provide a high water circulation rate and high velocity water injec-tion into the hydrotherapy device.  Reduced motor speed dur-ing periods of non-use results in substantial energy savings and a reduction in the noise generated by the device.

Abstract: Abstract: the present invention is directed to an apparatus for reproducing the bass components of an audio signal with a high degree of accuracy and minimal distortion, utilizing an enclosure of relatively small size. The apparatus com-prises a substantially sealed enclosure in combination with a radiating diaphragm driven by an electromagnetic transducer, the principal diaphragm restoring forces being the elastic forces exerted against the diaphragm surfaces by the gaseous medium engaging such surfaces.  The device is characterized by the elimination of the roll or surround joining the cone to the frame as heretofore always employed in reproducers of the air suspension type as the means for effecting a sealing of the enclosure, and the utilization of a rigid peripheral portion of the diaphragm immediately adjacent a parallel interior surface portion of the transducer mechanism to define a gap of minimal dimension, said gap being elongated in the direction of movement of the diaphragm, the clearance provided by said gap being maintained at minimal value con-sonant with movements of the diaphragm free from mechanical interference.

Abstract: DATA HASHING METHOD AND APPARATUS            Abstract of the Disclosure Hashing of a key data signal is accomplished by utilizing a pseudo-random number signal generator for generating a randomized signal in response to the key data signals and an output register for serially receiving the generated pseudo-random signal and for providing segments of the serially-received signal at its output. A counting circuit responsive to a preselected number of shift signals provides an output valid signal when the preselected number of shift signals has occurred and further shifts the pseudo-random number signal generator an amount corresponding to the preselected number of shift signals.  The method of the present invention utilizes the steps of presetting the pseudo-random num-ber generator and the counting circuit to an initialized state.  The counting circuit is then loaded with a pre-determined count whereupon key data is entered into the pseudo-random number generator so as to randomize the key data.  A valid signal is provided when a block of key data has been hashed and the steps of entering the key data and providing a valid signal upon the occurrence of each block of key data is repeated until all key data blocks have been hashed.

Abstract: APPARATUS AND METHOD FOR DETERMINING THE POSITION OF A GAS-SATURATED POROUS ROCK IN THE VICINITY OF A DEEP BOREHOLE IN THE EARTH   Abstract of the Disclosure Apparatus for determining the position of a gas-saturated porous rock in the vicinity of a deep borehole in the earth. The apparatus includes a source of seismic waves of selected characteristic, positioned at a selected point in the borehole, with an array of geophones positioned on the earth in known positions around the borehole.  These geophones are adapted to receive the seismic waves generated by the source in the borehole, after traveling downwardly through the earth to the formation and reflected from the formation, and to produce corresponding facsimile electrical signals. If the seismic waves from the source in their downward movement impinge upon a gas-saturated porous rock they will reflected, and therefore the signals from the geophones which are in path of the reflected waves will show a change of character.  If the reflection is observed while drilling at two or more known depths, the depth, azimuth, and radial position from the borehole of the gas-saturated rock can be determined.  Using the principle of reciprocity, the same measurements can be made by interchanging the positions of seismic source and receiving sensor.
